Abstract

PURPOSE:To communicate data simply between a terminal and a center device, by monitoring lines and making a receiver unoperated when the terminl transmits data. CONSTITUTION:In a terminal equipment 21, when a response request push button 16 is depressed after dialing, the relay of a transmission and receiving control part 27 is operated, and a data transmitter 26 is made unoperated, and a data receiver 24 is made operated. Next, when a link establishing signal is transmitted from a center device 19 and is received by the data receiver 24, the relay of the transmission and receiving control part 27 is made unoperated, and the data receiver 24 is made unoperated, and the data transmtter 26 is made operated. When a push button 13 for data transmission is depressed to transmit data and the response request push button 16 is depressed, a response request signal is transmitted to the center device, and said relay is operated to set the data receiving state. When data is transmitted from the center device, this data is displayed on a display part 25 through the receiver 24; and when data terminates or the response request signal is received, this relay is made unoperated, and the termial becomes the transmission state.
